I think you are mistaking the European way of policing with how cities are constructed. Most of the problems big cities have in the US come from high tolerance of overt crime, drug abuse, homelessness and more. - things that are mostly not tolerated elsewhere, and used to not be tolerated here either.
Half of the names of cities you have lived in are definitely mega-cities, or very close to being a mega-city. Manhattan, Brooklyn, Seattle, Palo Alto - none of these are even remotely similar to typical modern-day suburbs.
